swampy this may be a stupid question but do you put oil into filter before screwing it back onto car and also smear oil around rubber seal as if you dont put oil in sometimes the pump just bypasses the filter i normally half fill filter before putting it on 89 nissan looking foward to august and more travelling

Swampy does the engine fire on all 6 cylinders and idle at the correct speed when first started? If not start it with your foot on the accelerator so when it starts it runs up to 1000 rpm or so and the oil pressure will come up straight away. Don't worry it wont hurt the engine, just let it come back to idle as soon as the oil presssure is up. I had the same problem with a 2H and it ended up air locking the oil pump and not pumping at all. This caused a lot of mucking about including pulling the sump off twice, looking at the oil pick up pipe for cracks and trying to see if the oil pump drive was stripped or the gears broken. After finding nothing we had to prime the oil pump in through the pressure relief valve on the side of the pump with grease which worked and from then on I started it as above with no further problems. From memory it had a Ryco filter at the time and I always filled the new filter with oil before fitting.

Gday swampy, now you know your old 47 has a low oil pressure cut out so l wont talk about that but now that l think about it my old 60 did the same thing ,cut out on the first start of the day.With no throttle it would stop after a few seconds unless that first start was at a fast ide , got the pressure up before the cut out , but l cant remember the last time it happened.I used Ryco filters and valvoline oil but as it takes 10 odd liters of oil per change l started to buy Rimula X in 20 L drums and now l cant remember the last tme it happened
